AIR-HEATING- SYSTEM.

Application filed June 30, 1909. Serial No. 505,204.

To all whom it may concern:

Be it known that I, SIMON S. LAUGHLIN, citizen of the United States, residing at Colwich, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Air-Heating Systems, of which the following is a specification.

This invention relates to heating systems and refers Particularly to a system employed in connectlon with internal combustion engines.

An object of this invention is to utilize the heated air which is passed about the cyl- 'inders of an internal combustion engine heating a car or the like.

The invention }provision of an improved means whereby the eatedair is collected after assing about the cylinders of the engine an conveyed to the desired places to be heated.

A further object of this invention is the provision of an arrangement of air ducts whereby the eated air .is carried from the engineand led to the place to be heated, the ducts being provided with dampers or valves for cutting off the heated air to other portions of the ducts when heat is not desired at such portions.

The inventionhas for a still further object the provisionof an im roved means for conveying air to the cylinders of the internal combustion engine and for passing the air about such cylinders and finally conveying the air, after absorbing the heat cylinders to the location to be heated.

For a full understanding of the invention reference is to be had to the following de-' scription and accompanying drawings, in which:-

Figure 1 is a side elevation of the imroved system as applied to an internal com ustion en ine, the same being supported in a motor ve icle. Fig. 2 is a top plan view of the same, and Pi 3 is a sectional fragmentary view of t e main duct and one of the loop sections disclosing the valve or damper in a closed position and in dotted lines in an open position.

Corresponding and like parts are referred to in the following description. and indicated in all the views of the drawing by the same reference characters.

Referring to the drawing the numeral 10 the base or crank case of an internal combustion engine upon which are Specification of Letters .Patent.

has for another object the from the f upwardly from the air duct Patented July 19, 1910.

vertically positioned in longitudinal aline-' ment a plurality of cylinders 11, Disposed about each of the cylinders 11 are air jackets 12 which are connected at one side to a pipe ,13 longitudinally disposed at one side of the jackets 12 and communicated at its forward extremity with a cylindrical casing 14. The pipe 13 is connected to the upper end of the cylindrical casing 1&1 and receives air therefrom which is forced into the pipe 13 by the provision of a centrifugal fan located within the casing '14 upon the crank shaft 15 of the engine. In the drawings is disclosed the fan as being mounted upon the crank shaft 15, although intermediate shafts or gearing may be eInplo ed which are connected to the crank sha 15 to propel the fan. The fan comprises a pair of spaced rims 16 between which are engaged a plurality of radially extended plates 17 mounted upon a suitable hub 18 keyed to the shaft 15 which receives air from the central forward face of the cylindrical casing 14 which is provided with an opening 19 for the'same. Upon the opposite side of the jackets 12 a second pipe 20 is secured which is, communicated with each of the jackets '12 and extended backwardly where it terminates in an air 'duct 21 disclosedas being longitudinally positioned at one side of a motor vehicle and beneath the floor of the same. At intervals throughout the len th of the air duct 21 looped sections are ormed, which in the application of the device to a motor vehicle as is disclosed in the drawings, are preferably two .in number, the looped sections each comprising a pipe which extends 21 as at 22 where .it is turned inwardly and horizontally to the desired width and is then turned downwardly to an elbow 23 to dispose the lower-horizontal section 24 ina plane advanced from the upwardly curved section 22, which horizontal section 24 terminates in the side of the air duct 21.

Located within the air duct 21 is a damper or valve 25 hinged to the upper portion. of the duct 21 in such position as to admit of the engagement of the valve 25 against the opening into the section 22 to close the same at times. The valve 25 is mounted upon a stem 26 which extends outwardl to a convenient location upon, the side 0 the car as is disclosed in the drawing," where it is turned at substantially right angles to form aresilient arm 27 for engagement against finally to the discharge casing forward end lurality of jackets ers of said engine,

to said jackets unled from said jackthe serrated face of a segment 28 to frictionally retain the valve 25 in a desired position to admit of various quantities of air into the looped sections.

In the drawin the looped sections are shownas being located forwardly of the seats of the vehicle, one being located at the rear end of the hood while the second one 1 is positioned at the back of the opcrators The duct 21 is extended to the rear end of the vehicle where it is curved upwardly as at 29 to terminate centrally in one edge of a radiator 30 positioned at the back of the vehicle. The discharge casing 30 comprises a hollow rectangular chamber havlng the rear wall thereof perforated to admit of th e air conveyed bustion engine disposed in the of a motor vehicle, of a disposed about the cylin means for conveying air der pressure, an air duct ets, a plurality of looped eating at their opposite ends at intervals with said duct, a discharge casing communicatin with the extremity of said duct, and ositioned at the rear of the vehicle, said iseharge casing having a plurality of outlet openings therein, andvalves located at the intersections of said looped sections with said duct.

2. In combination with a vehicle and an internal combustion engine mounted in the forward end thereof, of a plurality of jackets disposed about the cylinders of said engine, means for introducing air into said jackets, an air duct connected to all of said jackets, looped sections communicating at intervals with said duct, a discharge casing positioned across the back of said vehicle and communicating with said duct, said discharge casing having a plurality of 0 )enings in the rear wall thereof to admit o the escape of heated air therefrom, and valves located in said duct at the intersections of said looped sections to direct heated air to the same at times.

3. In combination with a vehicle, a dashboard on said vehicle, seats transversely located on said vehicle and an internal combustion engine disposed in the forward end the same and the caused by the traveling of inwardly of the air about the sides drawing thereof.

In operation when the engine is set in motion the centrifugal fan is operated and a quantity of air is drawn in through the opening is desired of the car by to heat a portion admitting the heated air to the looped secof said vehicle, of jackets mounted about tions the orresponding-valve 25 is located said engine, means for introducing air into to c swung downwardly and to close the said jackets, an air ductextended from said jackets and positioned longitudinally beneath said vehicle, pipes forming looped sections communicating with said duct and y obpositioned against said dashboard and the the radiation from which will raise the temperature about such looped see- When it is not desired to heat the car the valves 25 are closed and retained in harge casing mounted across the rear of said vehicle and communieating with said duct, said casing having a plurality of openings therein for the escape sue position by the spring action of the of the heated air from said duct.
